Hi, Uri -
I think sales has already responded to your email...but just in case!
I have not seen a site done in Hebrew yet. I had googled it and sent you a possible plugin that would help "flip" the alignment. I have no idea if it will work! I've never used it or heard reviews on it, but I would definitely check it out.
Also, the content is all entered manually by you anyways, so if you enter it in Hebrew that is totally fine!
And finally, check out wordpress.org and search for "localization" to see if WordPress is in your language. Then your dashboard will be in Hebrew, and not English.
Good luck!
